An automated spraying device for coating lubricant onto rubber strip surfaces.

Abstract

This utility model discloses an automated spraying device for coating lubricant onto the surface of adhesive strips. It includes a frame with multiple sets of rollers rotatably connected to it. A support frame is connected below the frame, and multiple sets of plates are connected to the support frame. Multiple sets of springs are connected to one end of each set of plates. Scrapers are placed against one end of some of the rollers, and one end of each scraper is arc-shaped and fits against the outer wall of the roller. Each set of springs is connected to a corresponding scraper. In this utility model, a motor drives the corresponding rollers to rotate, and a synchronous pulley and belt drive some of the active rollers, while the rest are driven, conveying the adhesive strip to the spraying area. An electric slide rail drives the spraying assembly to reciprocate, spraying the adhesive strip. When the rollers are coated with lubricant, they contact the scrapers during rotation, and the scrapers remove the lubricant, preventing conveying deviation and improving the spraying effect. The scraped and fallen lubricant falls into the support frame and slides out to a collection device, making it widely applicable.

Description

Technical Field

[0001] This utility model relates to the technical field of rubber strip processing, and in particular to an automated spraying device for coating the surface of rubber strips with lubricant. Background Technology

[0002] During assembly or use, rubber strips often come into contact with and rub against other components (such as metal, plastic, and glass) (e.g., the sliding of car door and window rubber strips with glass, and the assembly of sealing strips with door frames). By coating the surface of the rubber strip with lubricant to form a uniform and stable lubricating layer, the coefficient of friction of the rubber strip surface can be reduced, frictional resistance can be reduced, and abnormal noise, jamming, or surface wear caused by excessive friction can be avoided.

[0003] In existing automated spraying equipment for rubber strip lubricants, the conveying system primarily relies on the rotation of conveyor rollers driven by a motor, achieving continuous conveying through the friction between the rollers and the rubber strip surface. Once the rubber strip is conveyed to the spraying area, an electric guide rail moves the spray gun along a preset trajectory to complete the spraying of the rubber strip surface. However, during the spraying process, splashed or dripping lubricant may adhere to the surface of the conveyor rollers. This lubricant reduces the friction between the conveyor rollers and the rubber strip, causing slippage and deviation during conveying. This can lead to the spraying position deviating from the preset trajectory, resulting in a less effective spraying. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automated spraying device for coating lubricant onto the surface of rubber strips.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automated spraying device for coating lubricant onto the surface of rubber strips includes a frame with multiple sets of rollers rotatably connected to it. A support body is connected below the frame, and multiple sets of plates are connected to the support body. Multiple sets of springs are connected to one end of each set of plates. Scrapers are placed against one end of some of the rollers. One end of each set of scrapers is arc-shaped and fits against the outer wall of the roller. The multiple sets of springs are respectively connected to the corresponding scrapers. Rods are connected to one end and the other end of the frame. The same set of electric slide rails are installed on the two sets of rods. The slide table of the electric slide rails is connected to a spraying assembly.

[0007] Preferably, a fan is installed at one end of the frame, a pipe is connected to one end of the fan, a pipe assembly is connected to one end of the pipe, the pipe assembly is connected to the frame, and multiple nozzles are connected to one end of the pipe assembly.

[0008] Preferably, a motor is installed at one end of the frame, and the output end of the motor is connected to a set of rollers through a coupling. Some of the rollers are connected to a set of synchronous pulleys at one end, and some rollers are connected to two sets of synchronous pulleys. The multiple sets of synchronous pulleys are driven by synchronous belts. The bottom of the frame is V-shaped and the conveying direction of the rubber strip is the lower end.

[0009] Preferably, each of the multiple sets of scrapers has a block connected to one end and the other end, and the multiple sets of blocks are slidably connected to the corresponding plates.

[0010] Preferably, one end of each of the multiple sets of scrapers is an inclined surface.

[0011] Preferably, one end of the spraying assembly is connected to a corrugated pipe, which passes through the corresponding rod.

[0012] Preferably, the material of the multiple sets of scrapers is polyurethane.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Through the coordination between the set rollers, scrapers, and frames, the motor drives the corresponding rollers to rotate, and then through the coordination of the synchronous pulley and the synchronous belt, it drives some rollers to rotate. These rollers are active, and the rest are driven. When the rollers convey the rubber strip to the spraying area, the electric slide rail is activated to drive the spraying assembly to move back and forth to spray lubricant onto the surface of the rubber strip. During the spraying process, lubricant may adhere to the surface of the rollers. As the rollers rotate, the adhered lubricant comes into contact with the scraper, and the scraper scrapes off the lubricant. To a certain extent, this avoids the problem of deviation in the conveying position caused by lubricant adhering to the roller surface, and improves the spraying effect to a certain extent. At the same time, the lubricant scraped off by the scraper and the lubricant that falls from the gap between the two sets of rollers during spraying will fall into the frame, slide out along the frame and fall into the collection device. It has a wide range of applications.

[0015] 2. By coordinating the fan, pipe assembly, and nozzle, the fan is started to deliver outside air through the pipe body into the pipe assembly, and then sprayed out through the nozzle. Before the adhesive strip enters the spraying area, the airflow sweeps its surface to remove dust and other impurities. To a certain extent, this avoids dust from blocking the contact between the lubricant and the adhesive strip surface, reducing the risk of coating peeling due to poor adhesion. It has a wide range of applications to a certain extent. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1, referring to Figures 1 to 5 An automated spraying device for coating lubricant onto the surface of rubber strips includes a frame 1, with multiple sets of rollers 2 rotatably connected to the frame 1. A frame body 6 is connected below the frame 1, and multiple sets of plates 7 are connected to the frame body 6. Multiple sets of springs 8 are connected to one end of each set of plates 7. The springs 8 drive scrapers 9 to adhere to the surface of the rollers 2. Scrapers 9 are placed against one end of some rollers 2. The scrapers 9 remove any lubricant that may adhere to the rollers 2. One end of each set of scrapers 9 is arc-shaped and fits into the outer wall of the rollers 2. The fitting arc-shaped structure reduces local frictional stress between the scrapers 9 and the rollers 2, avoiding wear on the surface of the rollers 2 or deformation of the scrapers 9 due to concentrated contact points. The multiple sets of springs 8 are respectively connected to the corresponding scrapers 9. One end of the frame 1 is connected to a... The rod body 15 has two sets of rod bodies 15 equipped with the same set of electric slide rails 16. The model of the electric slide rail 16 can be selected according to the actual situation. The electric slide rail 16 drives the spraying component 17 to move and spray the adhesive strip. The slide table part of the electric slide rail 16 is connected to the spraying component 17. The spraying component 17 can be a spray gun or other equipment. This is existing technology and will not be described in detail here. When the roller body 2 rotates, it will contact the scraper 9. The scraper 9 removes the lubricant that may adhere to the surface of the roller body 2. To a certain extent, this avoids the problem of the adhesive strip slipping due to the presence of lubricant on the surface of the roller body 2, which would cause the adhesive strip to shift and affect the shifting effect. At the same time, it avoids the need for manual cleaning of the roller body 2, thus ensuring the continuity of production to a certain extent.

[0024] In this embodiment, a fan 11 is installed at one end of the frame 1. The model of the fan 11 can be selected according to the actual situation. One end of the fan 11 is connected to a pipe body 12, and one end of the pipe body 12 is connected to a pipe assembly 13. The pipe assembly 13 is connected to the frame 1. One end of the pipe assembly 13 is connected to multiple sets of nozzles 14. When the fan 11 is started, outside air is delivered to the pipe assembly 13 through the pipe body 12 and sprayed onto the surface of the adhesive strip through the nozzles 14, blowing away the dust on the surface of the adhesive strip and avoiding the dust from affecting the spraying effect. It has a wide range of applications to a certain extent. A motor 3 is installed at one end of the frame 1. The model of the motor 3 can be selected according to the actual situation. The output end of the motor 3 is connected to a set of rollers 2 through a coupling. The motor 3 drives the corresponding rollers 2 to rotate. At the same time, the synchronous pulleys 4 and synchronous belts 5 drive some of the rollers 2 to rotate. The remaining rollers 2 are driven. The friction between the rollers 2 and the rubber strip is used to transport the rubber strip to the spraying area. Some rollers 2 are connected to a set of synchronous pulleys 4 at one end, and some rollers 2 are connected to two sets of synchronous pulleys 4. The multiple sets of synchronous pulleys 4 are all driven by synchronous belts 5. The bottom of the frame 6 is V-shaped and the conveying direction of the rubber strip is the lower end. The V-shaped bottom can collect the excess lubricant dripping during spraying and the lubricant scraped off by the scraper 9. The inclined design can use gravity to make the lubricant flow automatically along the inclined surface to the lower end, which is convenient for collection to external equipment, realizing the recycling and reuse of lubricant, while avoiding the accumulation of lubricant at the bottom of the frame 6. Multiple sets of scrapers 9 are connected to blocks 10 at one end and the other end. The blocks 10 are slidably connected to the corresponding plates 7, and the blocks 10 guide the movement of the scrapers 9. One end of each set of scrapers 9 is inclined, which facilitates smoother guidance of the scraped lubricant into the frame 6 and reduces lubricant residue at the scraper 9. One end of the spraying assembly 17 is connected to a bellows 18, which passes through the corresponding rod 15. One end of the bellows 18 is connected to other conveying equipment, such as a pump, to deliver lubricant into the spraying assembly 17. The bellows 18 has good flexibility and can be lengthened or shortened as the spraying assembly 17 moves when the electric slide rail 16 drives it to move back and forth, ensuring the continuity and stability of lubricant delivery and not affecting the normal operation of the spraying. The multiple scraper blades 9 are made of polyurethane. Polyurethane has good wear resistance and elasticity, which can not only fit tightly against the surface of the roller body 2 to effectively scrape off the lubricant, but also reduce wear on the surface of the roller body 2 and extend the service life of the roller body 2 and the scraper blades 9.

[0025] The working principle of this embodiment is as follows: When in use, after the motor 3 starts, it drives a set of rollers 2 to rotate via a coupling. The rollers 2, through the transmission cooperation of the synchronous pulley 4 and the synchronous belt 5, drive some of the rollers 2 to rotate synchronously, while the remaining rollers 2 are driven, forming a continuous adhesive strip conveying path. The adhesive strip moves along a preset direction under the support of multiple sets of rollers 2. Before the adhesive strip enters the spraying area, the fan 11 is started, and outside air is delivered to the pipe group 13 through the pipe body 12, and finally sprayed out through multiple sets of nozzles 14 to blow away dust and other impurities from the adhesive strip surface, preparing it for subsequent spraying. When the adhesive strip reaches the spraying area, the electric slide rail 16 drives the slide table to move back and forth according to a preset program, driving the spraying assembly 17 to evenly spray lubricant. During the spraying process, lubricant may adhere to the surface of some rollers 2. As the rollers 2 rotate, the arc-shaped scraper 9, under the elastic force of the spring 8, always adheres to the surface of the rollers 2, automatically scraping off residual lubricant and preventing the adhesive strip from shifting due to roller slippage, thus ensuring the spraying effect to a certain extent. The scraped lubricant and the lubricant dripping through the gap between the two sets of rollers 2 during spraying fall into the frame 6 and automatically slide out along the inclined surface of the frame 6 to the collection device, realizing the recycling and reuse of lubricant. The motor 3, fan 11, electric slide rail 16 and other equipment are linked through the electrical control system, and each link operates automatically according to the preset sequence without manual intervention. From rubber strip conveying, surface cleaning, lubricant spraying to roller 2 cleaning and recycling, a closed-loop automated operation is formed, which improves production efficiency and coating quality stability to a certain extent.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
